+# Sea Haven Governance
+
+**Standards authority:** engineering-handbook · **Status authority:** Jira
+
+## Routing
+
+- Product / feature work → DEV
+- Infrastructure and platform → PLAT
+- Security → SEC
+
+## Branches
+
+`feature/`, `fix/`, `hotfix/`, `chore/`, `docs/`, `refactor/`, `release/` + kebab-case description.
+No Jira keys in branch names.
+
+## Pull Requests
+
+**Title:** `type(scope): description (DEV-123)` — every non-exempt PR ends with its Jira key.
+
+**Body sections (in order):** Summary · Validation · Tests · Notes — use "None." when a section is empty.
+State verifiable facts only. Do not cite the handbook to justify changes.
+
+Allowed types: `feat` `fix` `docs` `style` `refactor` `perf` `test` `build` `ci` `chore` `revert` `release`.
+
+## Security Gates
+
+Changes touching payment flows, authentication, secrets, IaC/IAM, or untrusted user input require
+a security review. IAM role, policy, or resource-permission changes require cross-family review.
+Lambda handler-signature changes alone do not trigger cross-family review.
+
+## CI and SHA Pins
+
+Pin every GitHub Actions ref to a full commit SHA with an inline version comment:
+
+```yaml
+uses: actions/checkout@abc123def456 # v4.1.0
+```
+
+The deterministic global pre-push security hook must not be bypassed (`--no-verify` requires
+explicit approval). Linting stays in CI; do not gate on it locally.
+
+## Repository Note
+
+Generic governance applies. Route product work to DEV, platform/infra to PLAT.
